These guys could not find a bolt in a jar of bolts. They charge me 386.00 dollars and did not fix the problem. They put a rotar and rator cap on calming that was the problem. I took my truck to someone else, told them what I told the Auomedic guys, they ran a compression check on my fuel pump and found the problem. The fuel pump....Why the Automedic guys couldn't or would have done the samething is beyond me. If you want to throw your money aways have these guys "work" on your car.
